aria-hidden="true">#</a> JVM</h2><p><strong>为什么要学习 JVM？</strong> 对于 Java 程序员来说，JVM 帮助我们做了很多事情比如内存管理、垃圾回收等等。在 JVM 的帮助下，我们的程序出现内存泄漏这些问题的概率相对来说是比较低的。但是，这并不代表我们在日常开发工作中不会遇到。万一你在工作中遇到了 OOM 问题，你至少要知道如何去排查和解决问题吧！并且，就单纯从面试角度来说，JVM 是 Java 后端面试（大厂）中非常重要的一环。不论是应届还是社招，面试国内的一些大厂，你都会被问到很多 JVM 相关的问题（应届的话侧重理论，社招实践）。</p><p><strong>只有搞懂了 JVM 才有可能真正把 Java 语言“吃透”。</strong> 学习 JVM 这部分的内容，一定要注意要实战和理论结合。</p><p><strong>什么时候可以开始学习 JVM 呢？</strong> 理论上来说，学完了 Java 基础就可以学习 JVM。不过，由于 JVM 部分的知识还是有点难度的。我建议你可以在熟练使用 Java 语言解决一些实际问题之后（比如搭建网站）再开始学习 JVM。另外，学习 JVM 之前，最好提前学习一下并发编程。</p><p>书籍的话，<strong><a href="https://book.douban.com/subject/34907497/" target="_blank" rel="noopener noreferrer">《深入理解 Java 虚拟机》<span><svg class="external-link-icon"

套接字服务器等网络编程,并且性能以及安全性等很多方面都非常优秀。</li><li>我们平常经常接触的 Dubbo、RocketMQ、Elasticsearch、gRPC、Spark、Elasticsearch 等等热门开源项目都用到了 Netty。</li><li>大部分微服务框架底层涉及到网络通信的部分都是基于 Netty 来做的，比如说 Spring Cloud 生态系统中的网关 Spring
